FIELD OF THE PRESENT INVENTION

The present invention provides a “bottle structure for containing different beverages therein” with feature in easily and quickly mixing two beverages of different flavors each other without changing the usual drinking practice so that not only the advantages of available convenience in hand holding and the effortlessness in rotating exertion can be achieved, but also the beneficial effect in reducing manufacturing cost for mass production can be accomplished.

BACKGROUND OF THE INVENTION

Thanks to novelty requirement of pursuing different flavor in beverage from the consumers, to blend beverages in different flavors for drinking becomes the prevalent habit. Accordingly, the businessmen, who commercialize the packed beverage, all try their best to design various containers filling with different drinks therein without mixing each other to avoid consumers from dirty and touching the finger in mixing procedures of two different beverages. For examples, the Japanese patents published in numbers of P2003-12015A, P2004-83022A, P2004-323097A, P2004-338751A, P2005-22706A and P2006-103781A; the USA patent in number of U.S. Pat. No. 3,968,872 as well as the Taiwan patents in number of 093212058, 093212059, 093207276 (certificate No. M 262462) and I 271358, which all owned by the applicant of the present invention. All products belong to this category. By inducing all the designs for those products in prior arts aforesaid, a second beverage is stored in the bottle cap, which is usually employed for screwing together with associated bottle, so as to separate the first beverage in the bottle in isolated manner. Taking Taiwan patent No. I 271358 of the applicant as example, as shown in the FIGS. 1 and 2, the structure comprises a bottle 1 for filling first beverage G, a bottle cap 2 for filling second beverage R and a dividing disk 3 disposed in the bottle cap 2 to avoid the second beverage R for leaking out. By screwing the bottle cap 2 together with spout opening 101 of the bottle 1, the second beverage R therein is kept away from the first beverage G in the bottle 1 in separated and isolated manner (as shown in the FIG. 1). During mixing operation for drinking, the bottle cap 2 is properly rotated to screw with the threaded spout opening 101 of the bottle 1 for displacing the dividing disk 3 so that the second beverage R in the bottle cap 2 flows downwards into the bottle 1 to mix with the first beverage G of different flavor therein (as shown in the FIG. 2).

After the mass production through molding the patent No. I271358 owned by the applicant of the present invention, the features and the effects of the output product completely meet the anticipated consequence and requirements in hygiene and drink safety so that it has been favored and commercialized by some state-run enterprise and individual enterprise through joint-venture contracts. After commercializing the product for some time, a few complaints from women consumers reflects that rather relative force is required to rotate the cap during mixing operation for drinking so that the holding the bottle become not used to handle. The drawbacks incurred are finally found as below by further studying;

1. The bottle cap 2 is bulky for filling more second beverage R so that consumers become awkward in handling the bottle 1 other than extra force is required to turn the bottle cap 2 to displace the dividing disk 3 therein, which is more difficult than that happening in the conventional bottle cap without conservation of second beverage R therein. The more quantity of second beverage R is required for filling in the bottle cap 2, the more serious situation becomes due to more bulky of the bottle cap 2 is needed. Accordingly, the complaints from the consumers due to inconvenience are unavoidable.

2. The shape and handling means in the packaging and wrapping case associated must be altered to fit with the enlargement of the bulky bottle cap 2 so that the handling method in the transportation and space management of the stacking mode in the warehouse should be changed concurrently, which incurs extra cost out of original expectation.

Additionally, the container structure of the Taiwan patent No. M296853, which is different from that described above, comprises a “first outer container”, which is configured with flexible wall of pleated corrugation with expansibility, for filling “first beverage” and a “second inner container”, which is nested in the “first outer container”, for filling second beverage so that the “second inner container” is deformed into rupture to let second beverage mix with the first beverage in the “first outer container” directly when the “first outer container” is pulled in stretched manner during drinking operation. Although such structure gets rid of the need in rotating the bottle cap, the drawback is incurred with the flexible wall configuration of pleated corrugation with expansibility in the first container. Namely, the malignantly or unexpectedly mixing two beverages with each other can not be avoided from the unanticipated or accidental pulling action on the “first outer container”. For some beverages of special requirement in flavor taste, the mixing time is critical in right before drinking to have fresh flavor taste. The unexpected mixing time, which happened long time ahead of drinking time, becomes a bad taboo in product design obviously.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a “bottle structure for containing different beverages therein”, which comprises an outer container, a tubular inner container and a cap, wherein, said outer container of an integral hollow body includes a holding hollow cavity encompassed by a open top surface, a bottom surface and a barrel-shaped lateral surface, a protruding round stud with external male thread on the outer peripheral thereof being integrally disposed in the internal center of the bottom surface, and a neck spout opening with external male thread on the outer peripheral thereof; said inner container of hollow tubular body has an external male thread formed on the outer peripheral of the upper end thereof and an internal female thread formed in the inner brim of the lower end thereof; and said cap includes an open hollow cavity encompassed by a closed top surface, an open bottom surface and a cylindrical lateral surface with internal female thread formed inner wall thereof, a protruding nut hoop with internal female thread formed inside thereof being integrally disposed in the internal center of the top surface.
